Wide Rear Ends - YFZ450 Axle Install - How-To

11. Before you're ready to reinstall the axle into the rear carrier assembly, you must smear grease onto the center section of the axle. Again, this aids in the ease of removing the axle in the future as well as keeps moisture from entering. Now gently slide the axle back into the carrier.		12. If the axle hangs up slightly during the install process, put the rear axle hub nut in backward and use a rubber mallet again to persuade it to go the remainder of the way.
	13. Grease the exposed splines on the axle so you may slide on the brake rotor hub. Tap on the hub to ensure that it's seated all the way in the axle housing. When this is done, you may now thread on the axle nut. It should be able to go on a majority of the way without serious strain.	14. Slide your sprocket over the sprocket hub and install. Be sure to torque all nuts and bolts to factory specifications.
15. Reinstall the rear brake caliper. It never hurts to add a slight amount of blue Loctite to ensure that the bolts don't come out.		16. With the caliper installed, you can have someone step on the rear brake pedal while you completely tighten the rear axle nut. Make sure to secure the axle locknut with the two setscrews.
	17. Install the two rear hub assemblies and secure with the new cotter pins. It's wise to tighten down with an air impact wrench.	18. Remount your rear tires and you're ready to shred!

Although this is a semi-high-dollar item, the installation procedure is relatively easy. Just make sure that you take your time and work patiently. So why are you still sitting there? Get out and ride!
